hey man. no, theyre not hard to install. the only thing difficult is getting the gauges behind the fuel and temp needles without throwing them outta wack. you put em on (guessing you know how to take off the gauge cluster already), wire the red wire into the back of the dimmer switch (orange wire iirc) and then pinch the black one into one of the screws that goes into the frame of the car behind the gauges and voila!Guitardude and Midrange, are they hard to install? Do I have to wire anything up?
